Quality measurement
DiaBeadsTM always supplies our valuable customers with world-class products, confirmed by the reliable Total Quality Management system.
The most important of our quality guarantees is the trustworthy wear-rate, compression strength tested to provide maximum efficiency to customers in the field.
Compression Strength Testing
1 The result of our DiaBeadsTM testing showed as kgf/mm2.
- - if the size “mm” is input, mm2 is calculated automatically by the computer.
- - As the result, the standard size of each product is the same.
2 Three step checking : 20~100 pieces per time
- - First : pre-sintering (choose sintering or recycling)
- - Second : post-sintering (compare with the result of pre-sintering)
- - Third : final check after separation of roundness
3 Testing Machine
- - universal compression strength machine
- - max kgf : 1000kgf
- - model : NA-1000 (Nanotech, Korea)
- - zig : polished surface zig of Si3N4 Materials
- - automatic control and display by computer
